In two dimensional electron systems, magneto oscillations underpin the Landau quantization of electrons under an external magnetic field. In addition to the conventional Shubnikov-de Haas (SdH) oscillations, a variety of novel low-field oscillations have been investigated, primarily in GaAs-AlGaAs heterostructures, where transition of electrons between Landau levels can lead to oscillations in longitudinal resistance as the magnetic field (\(B\) ) is varied. These transitions are typically enabled by phonon-mediated resonances [1]}, [2]}, [3]}, [4]}, [5]}, [6]}, strong Hall field [6]}, [8]}, [9]}, [10]} or microwave illumination [11]}, [12]}, [13]}, [14]}, [15]}. In recent times, quantum oscillations have led to key discoveries in graphene and other van der Waals heterostructures, including unconventional Berry's phases [16]}, [17]}, the Hofstadter spectrum [18]} and magnetophonon resonances [19]}. These studies were primarily done in the near-equilibrium limit with a small electric field applied laterally. The fate of quantum Hall effect and magneto oscillations in graphene when subjected to strong electric fields and high currents has received much less attention [20]}, [21]}, [22]}, [23]}. Importantly, such non-equilibrium effects are relevant in the context of electron interferometers using edge channels for quantum information processing [24]}, [25]}, generation of excitations such as magnetoplasmons in the edge channels [26]} and for the application of the quantum Hall effect as a resistance standard [23]}, [28]}.
